Speaking on comedian Marc Maron’s podcast, Smith says, “It was difficult. I’ve never been involved in a situation like that where one component is not in the box at all. It was f**king soul crushing.

“I mean, a lot of people are gonna be like, ‘Oh, you’re just trying to blame the movie on him’. I had no f**king help from this dude whatsoever.”

But Smith is full of praise for Willis’ co-star Tracy Morgan, adding: “He’s a f**king dream. Tracy Morgan, I would lay down in traffic for. Were it not for Tracy, I might’ve killed myself or someone else in the making of that movie.”
